This version contains my patch that adds support for the proprietary
VideoCore mailbox message for reading the kernel command line, so
patches aren't needed anymore.
This consolidates version information, archive's download location,
filename and SHA256 checksum into version.sh. This file is then sourced
from the port script and toolchain build script.
The version.sh script contains the following variables:
- QEMU_VERSION - Version number
- QEMU_ARCHIVE - Filename
- QEMU_ARCHIVE_URL - Full url to download location
- QEMU_ARCHIVE_SHA256SUM - The SHA256 checksum
